Device for marking material

ABSTRACT

The marking of the material is made from a flexible strip comprising a continuous paper-like material having a coating of plastic material which may be released from the paper-like material when heated to a predetermined degree, the heated plastic coating being released on the edge of a stack of material when the proper heat is applied to the paper side of the strip.

, ergmar .I 2,975,091 3/1961 Tobey 117/37 R 4 Claims, 5 Drawing Figures PATENTED FEB 4191s DEVICE FOR MARKING MATERIAL The present invention relates to marking the edges of stacked material particularly after the material has been cut to a particular form wherein the material is to be later processed into garments and other articles.

In the past this cut-out material was marked with a notching knife. However, most of the cloth being used in garments and other items is made either wholly or partially from synthetic material which does not adhere to itself as does cotton or wool; therefore the synthetic material slides away from the notching knife making the marking of the material quite difficult.

One object of the invention is to provide a more positive method of marking cut-out stacks of materials.

Another object of the invention is to provide a simple, compact and practical device for applying the markings to the stack of material.

A further object of the invention is to provide a method and device for the marking which is safe to handle.

While several objects of the invention have been set forth, other objects, uses and advantages will become apparent as the nature of the invention is more fully disclosed in the following description when taken in connection with the accompanying drawings, in which:

FIG. 1 is a side view of the device.

FIG. 2 is a top plan view of the same with parts broken away to show vital parts of its internal mechanism.

FIG. 3 is an enlarged fragmentary perspective view showing the manner in which the tape is presented to the material stack and the method in which the marking is applied to the material.

FIG. 4 is a fragmentary perspective view of a stack of material to be marked.

FIG. 5 is a view similar to the view shown in FIG. 4 after the material has been marked.

Referring to the drawings, represents a plurality of layers of material which may hereinafter be referred to as a stack and which has been cut according to a pattern 12. Each of the layers of material is marked as shown at 16 and 18 in FIG. 5. The markings extend downwardly from the pattern 12 on each side of the mark 20 carried by the pattern.

The marking material 22 consists of a colored plastic material carried on a paper web 24. While the web is designated as paper it may be of any suitable material, and while the marking material is designated as a plastic it also may be of any suitable type of material. The plastic material is compounded to remain in a stable, untransferable state at normal room temperature, and to be formed into a semi-liquid transferable state by the application of heat, that is, when the proper heat is applied and the tape is pressed against the side of the stack of material a portion of the plastic 22 will be transferred to the material extending downwardly in two rows from the pattern 12 evenly spaced at each side of the pattern mark 20, as shown in FIG. 5.

The tape must be presented to the edge of the stack 10 parallel with the edges of the stacked pieces, which is done by the operation of the device.

The device is provided with a base 30 having a portion 30 extending outwardly and under the edge of the stack 10 as shown in FIG. 1. The tape T may or may not be carried within a cassett 32 adjacent one end of the base having an opening 32. The tape is fed about a pair of posts 34 and 36 and between a pair of power driven pinch rolls 40 and 42. There is provided a solenoid motor carried within the housing 44 having an arm 46. Attached to the outer end of the arm 46 is a heated plate 48. The solenoid and heating plate are electrically operated and heated by an electric current supplied through the cable 50. The solenoid is operated by a switch button SI positioned within a handle 53 wherein the arm 46 is moved outwardly in the direction of the arrow (FIG. I) by the action of "the solenoid pressing the heated plate 48 against the edges 10 of the material 12 as shown in FIG. 5 leaving a deposit of the plastic as shown at 16 and 18 after which the arm 46 is returned to its rest position by the action of compression spring 55 after which the device may be moved to another location on the pattern such as that shown at 20, and the operation repeated.

In operating the device the edges I0 of the material must be pressed snugly in contact with the shoulders 52 and 54 of the device as shown in FIGS. 1, 2 and 3 and the portion 30' of the device extended beneath the stack as illustrated best in FIG. 3.

While this method and device for marking the edges of material is shown and described for a specific device, it is not intended as a limitation as the scope of the invention is best defined in the appended claims.

I claim:

1. A device for marking the edges of a stack of material formed from a plurality of individual layers, comprising in combination:

a. a base;

b. means for rotatably supporting a roll of marking tape on said base, said tape having a heatdissolvable material on one side thereof;

c. means for supporting the side of the tape carrying the heat-dissolvable material in close proximity to the edges of the stack of material;

(1. a heated plate fixedly supported on said base;

e. means for moving the heated plate in contact with the edges of the stack of material for engaging the same for depositing at least a portion of the material carried by the tape on the edges of the stack of material, and

f. a motor having means connected to the heated plate for operating the same.

2. A device for marking the edges of a stack of material as claimed in claim 1 wherein the device is provided with means for moving the said tape to different locations with respect to the heating plate.

3. A device for marking the edges of a stack of material as claimed in claim 1 wherein means are provided for moving the heated plate through a single outward and inward operation.

4. A device for marking the edges of a stack of material as claimed in claim 1 wherein means are provided to keep the heated plate in withdrawn position when not being operated by the said motor.
